"When faced with a research job which entailed the computation of at least 1770 phi coefficients, some way to reduce the work was sought. The answer was the accompanying table." The formula given was: "for various values of p 12 , [and] for values of [Equation omitted] from .20 to .80." (PsycInfo Database Record (c) 2025 APA, all rights reserved)
